We're glad to run purely free software for our network. 6IRCNet operators would like to thank all the contributors of those great pieces of software - without you our network wouldn't exist.
We use InspIRCd 2.0 on all servers in the network. We believe that it's the most advanced and featured IRCd being at the same time very stable.
 Synchronizing and development
We've chosen git for synchronizing our configs and developing new software for the network - thankfully, all projects we depend on use it, so it's easier for us to develop patches.
 System software
Our servers run GNU/Linux and FreeBSD.
